Description

Technical Field

[0001] The utility model relates to the technical field of OLED protective film production, in particular to an integrated production system for inkjet printing, cutting, cleaning and testing of OLED protective films. Background Art

[0002] OLED protective film is a key component of OLED display screens and is widely used in consumer electronics such as smartphones, tablets, and TVs.

[0003] In the traditional OLED protective film production process, after production, the OLED protective film needs to go through steps such as coding, cutting, cleaning, and testing. These steps are often performed independently, requiring multiple devices and manual operations. Each step operates independently, and material transfer is frequent, resulting in low overall production efficiency. At the same time, in this process, since the OLED protective film has extremely high requirements for the cleanliness of its surface treatment, the film inspection accuracy requirements are relatively high. However, the defects of the current OLED protective film are not only diverse in types, but also in various forms. Some may be very small and difficult to accurately identify with automated equipment. Therefore, the inspection of OLED protective film requires manual defect screening, which is the most time-consuming step in the entire OLED protective film production process. In order to further improve the efficiency of OLED protective film production, the efficiency of manual inspection of OLED protective film must be improved.

[0004] However, during the production process, OLED protective films undergo multiple transfers before being stored for inspection. Not only is the surface of the OLED protective film easily contaminated by unclean indoor air, making cleaning and inspection more difficult and impacting overall production efficiency, but also, during final storage, the stacking of the protective films can easily cause friction between the OLED protective films, generating static electricity and absorbing impurities in the air, further increasing the difficulty of subsequent inspections and affecting the inspection efficiency of the protective films. Furthermore, different OLED protective films have different materials and thicknesses, and the inspection requirements and ambient temperature and humidity vary significantly during inspection. Therefore, when inspecting OLED protective films, it is necessary to manually select a detection device that is suitable for the light intensity and centrifugal fan height, or manually adjust the light intensity and centrifugal fan height. This is a cumbersome process that affects the inspection efficiency of the protective film, directly leading to a decrease in the overall production efficiency of OLED protective films.

[0005] Therefore, it is necessary to improve the detection efficiency of OLED protective film and thus improve the overall production efficiency of OLED protective film, and provide an integrated production system for OLED protective film coding, cutting, cleaning and detection with high production efficiency.

DETAILED DESCRIPTION

[0027] To help those skilled in the art better understand the present invention, the present invention is further described in detail below with reference to the accompanying drawings. The embodiments described herein are merely a portion of the present invention, not all of the present invention. All other embodiments derived by those skilled in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0028] refer to Figure 1 As shown, an integrated production system for coding, cutting, cleaning and testing of OLED protective films includes a coding device 1 for coding identification information of the OLED protective film, a cutting device 2 for cutting the OLED protective film, a cleaning device 3 for cleaning the upper and lower surfaces of the OLED protective film, a storage bin 4 for storing the cleaned OLED protective film, and a detection device 5 for detecting defects in the OLED protective film on the storage table.

[0029] Specifically, the inkjet printer 1, cutting device 2, cleaning device 3, and storage bin 4 are sequentially arranged on a conveyor line 6; the conveyor line 6 is located within a production room 7, and the clean room 7 is equipped with a fresh air system 8 for supplying clean air into the production room 7. The OLED protective film passes through the inkjet printer 1, cutting device 2, cleaning device 3 in sequence along the conveyor line 6, and is then stored in the storage bin 4. The inspection device 5 is located on one side of the storage bin 4 and is used to inspect the OLED protective film for defects.

[0030] The OLED protective film is transported sequentially along conveyor line 6, passing through coding device 1 for surface marking. It is then cut to size by cutting device 2, cleaned on both the upper and lower surfaces by cleaning device 3, and finally transported to storage bin 4 for storage. Operators remove the cleaned protective film from storage bin 4 and bring it to inspection device 4 for inspection. Conveyor line 6 seamlessly connects the coding, cutting, cleaning, and inspection processes of the produced OLED protective film, achieving a highly automated and continuous production process, significantly improving the overall production efficiency of OLED protective film.

[0031] Specifically, the fresh air system includes an air inlet duct (not shown in the figure), an air outlet duct (not shown in the figure), an air inlet fan (not shown in the figure), an air purifier for purifying outdoor air (not shown in the figure) and an air outlet fan (not shown in the figure). A fresh air inlet (not shown in the figure) and an air outlet (not shown in the figure) are provided on the side wall of the dust-free production room 7; the air inlet fan is connected to the air purifier and the air inlet duct in sequence, and the air inlet duct is connected to the fresh air inlet, and the air outlet fan is connected to the exhaust outlet through the air outlet duct.

[0032] By setting up separate air inlet fans and air outlet fans, as well as air inlet pipes and air outlet pipes used in conjunction with the air inlet fans and air outlet fans, the air inlet fan draws in air from outside the production room 7, and the outdoor air is purified by the air purifier and then transmitted to the production room 7 through the air inlet pipe; the air outlet fan draws out the exhaust gas in the room and discharges it to the outside of the production room 7 through the air outlet pipe, thereby realizing the circulation of new and old air inside and outside the production room 7, and also ensuring the cleanliness of the air in the production room 7.

[0033] By setting up the fresh air system 8, the air in the production room 7 is kept clean, thereby preventing the surface of the OLED protective film from being contaminated by the unclean air in the room, which makes the cleaning and testing of the OLED protective film more difficult and affects the overall production efficiency. This is conducive to improving the cleaning and testing efficiency of the OLED protective film, thereby improving the overall production efficiency.

[0034] refer to Figure 2 and Figure 3 As shown, the storage bin 4 includes a frame 41 disposed at the end of the conveyor line 6 and a control device (not shown) disposed on one side of the frame 41. The frame 41 is provided with a storage tank 42. A pressure sensor 43 is disposed at the bottom of the storage tank 42 for detecting weight changes within the storage tank 42. The pressure sensor 43 can accurately detect the total weight change of the OLED protective film in the storage tank 42, thereby indirectly reflecting the number of protective films or the stacking status. This can effectively prevent overloading of the storage tank 42 and effectively utilize the capacity of the storage tank 42.

[0035] The frame 41 is provided with a film removal port 47 for removing the OLED protective film from the storage tank 42 on the side away from the conveyor line 6, and the detection device is located on the side of the film removal port 47. The storage tank 42 is provided with a notch on the side close to the film removal port 47 for facilitating the removal of the OLED protective film from the storage tank 42.

[0036] The receiving trough 42 is located at the end of the conveyor line 6, and a guide roller 44 is provided on the frame 41 of the receiving trough 42 near the conveyor line 6. The guide roller 44 is provided on the frame 41 of the receiving trough 42 near the conveyor line 6 to guide the OLED protective film into the receiving trough 42, ensuring that the OLED protective film can enter the receiving trough 42 smoothly and accurately when being conveyed to the receiving trough 42.

[0037] A laser rangefinder 45 is mounted on a frame at the top of the storage tank 42 to measure the thickness of the OLED protective film and detect changes in the thickness of the OLED protective film within the storage tank 42. By detecting changes in the thickness of the stacked OLED protective films within the storage tank 42, both the thickness of the OLED protective film and the number or stacking status of the protective films can be determined. This effectively prevents overloading of the storage tank 42 and ensures efficient utilization of the storage tank 42's capacity.

[0038] In this embodiment, the laser ranging sensor 45 measures the thickness of the OLED protective film by pre-measurement of the vertical distance between the laser ranging sensor 45 and the bottom of the storage tank 42, which is recorded as A. Then, when the first OLED protective film enters the storage tank 42, the laser ranging sensor 45 measures the vertical distance between the laser ranging sensor 45 and the surface of the first OLED protective film, which is recorded as B. Subtracting A from B yields the thickness of the OLED protective film. In this embodiment, the laser ranging sensor 45 is located directly above the center of the storage tank 42, which is aligned with the center point of the end of the conveyor line 6.

[0039] A first ion blower 46 is provided on the frame on one side of the laser ranging sensor 45. The first ion blower 46 removes static electricity from the surface of the OLED protective film entering the storage slot 42. It also removes static electricity generated by friction between the incoming OLED protective film and other incoming OLED protective films. This prevents dust and other impurities generated during production or remaining in the air from being re-adsorbed onto the OLED protective film, thereby increasing the difficulty of detection by the detection device 5 and affecting the efficiency of subsequent detection, thereby improving overall production efficiency.

[0040] The pressure sensor 43, laser ranging sensor 45, and first ion blower 46 are electrically connected to the control device. In this embodiment, the laser ranging sensor 45 pre-measures the vertical distance from the laser ranging sensor 45 to the bottom of the storage tank 42 when the storage tank 42 is empty, which is recorded as A. Then, when the pressure sensor 43 detects a pressure change in the storage tank, it sends a corresponding signal to the control device. After receiving this signal, the control device detects that the first OLED protective film has entered the storage tank 42. At this time, the control device measures the vertical distance from the surface of the first OLED protective film detected by the laser ranging sensor 45, which is recorded as B. The thickness of the OLED protective film can be obtained by subtracting A from B.

[0041] The detection device 5 includes a device body 51 and a telescopic bracket 52 respectively arranged on both sides of the device body 51, and a second ion blower 53 is provided between the telescopic brackets 52. One side of the device body 51 is provided with a first driving mechanism (not shown in the figure) for driving the telescopic bracket 52 to synchronously extend and retract, and a temperature and humidity sensor 54 for detecting the temperature and humidity of the external environment.

[0042] Among them, a light transmission inspection table 55 is provided above the device body 51; a backlight panel 56, a lifting assembly 57, a backlight panel 56 arranged above the lifting assembly 57 and a second driving mechanism (not shown in the figure) for driving the lifting movement of the lifting assembly 57 are provided in the device body 51, the temperature and humidity sensor 54, the first driving mechanism and the second driving mechanism are all electrically connected to the control device, and the control device is used to control the height and brightness of the backlight panel 56 according to preset detection requirements and the thickness of the OLED protective film; the control device is also used to control the height and operating power of the second ion blower 53 according to the temperature and humidity of the external environment and the thickness of the OLED protective film.

[0043] Specifically, the preset detection requirements may include setting the required light brightness for various materials, colors, and uses of the OLED protective film, and adjusting the brightness based on the thickness of the OLED protective film. The control device pre-stores a number of preset detection requirements and the required light brightness corresponding to the thickness, as well as the corresponding backlight panel 56 brightness and height.

[0044] The control device obtains the thickness of the OLED protective film through the laser ranging sensor 45, and then controls the height and brightness of the backlight panel 56 according to the preset detection requirements and the pre-stored data corresponding to the thickness of the OLED protective film, thereby achieving a range adjustment of the light intensity after the light generated by the backlight panel 56 is transmitted to the translucent inspection table, so that the light intensity on the translucent inspection table can adapt to the inspection requirements of OLED protective films of different thicknesses and different preset detection requirements, which is beneficial to improving the accuracy and detection efficiency of the OLED protective film inspection, thereby promoting the efficiency of the detection link and improving the overall production efficiency.

[0045] The control device also pre-stores the ion blower's operating power and required height for various ambient temperatures, humidity levels, and OLED film thicknesses. Different OLED film thicknesses require a suitable ion blower height to ensure uniform airflow across the film under test. Different ambient temperatures and humidity levels also require different ion blower operating powers to ensure effective static removal.

[0046] The control device obtains the temperature and humidity of the external environment through the temperature and humidity sensor 54, and then controls the height and operating power of the second ion blower 53 according to the temperature and humidity of the external environment and the thickness of the OLED protective film, so as to adjust the brightness of the backlight panel 56 and the height and operating power of the second ion blower 53, thereby improving the inspection efficiency and inspection quality of the detection link, saving the time spent on the manual inspection link, and thus improving the overall production efficiency of the OLED protective film. For example, in an environment with low humidity, the number of charged particles in the air is small, which is conducive to the operation of the ion blower. At this time, the operating power of the ion blower can be appropriately increased to improve its purification effect or static electricity removal effect. If the thickness of the OLED protective film is large, a higher ion blower height is required to ensure that the airflow evenly covers the OLED protective film being tested.

[0047] refer to Figure 4 As shown, the telescopic bracket 52 includes a telescopic sleeve 521 and a telescopic rod 522. One end of the telescopic rod 522 is slidably connected to the telescopic sleeve 521, and the other end is fixedly connected to the second ion blower 53. The first driving mechanism is used to drive the telescopic rod 522 to extend and retract within the telescopic sleeve 521. When the telescopic rod 522 is extended within the telescopic sleeve 521, the first driving mechanism is used to lift the first ion blower 46, thereby raising the first ion blower 46. When the telescopic rod 522 is shortened within the telescopic sleeve 521, the first driving mechanism is used to move the first ion blower 46 downward, thereby lowering the first ion blower 46, thereby adjusting the height of the first ion blower 53.

[0048] Preferably, reference Figure 4 、 Figure 5As shown, the telescopic rod 522 is provided with a through hole (not shown in the figure) and a screw 5221, and the second ion blower 53 is provided with a fixing plate 531 at both ends. The fixing plate 531 is provided with a screw hole (not shown in the figure) that matches the through hole (not shown in the figure), and the screw 5221 passes through the through hole (not shown in the figure) and is threadedly connected to the screw hole (not shown in the figure), and a rotating handle 5222 is fixed on the nut of the screw 5221 to facilitate the rotation of the screw 5221. By rotating the rotating handle 5222, the second ion blower 53 is fixedly hinged on the telescopic rod 522. The screw 5221 can be rotated according to actual conditions to adjust the fixing angle of the second ion blower 53, thereby adjusting the angle of the air supply.

[0049] refer to Figure 4 and Figure 5 As shown, the first ion blower 46 and the second ion blower 53 each include an aluminum blower housing 461 and a deflector (not shown in the figure) arranged on the aluminum blower housing 461, a blower body 462 and a cooling fan 463 are provided in the aluminum blower housing 461; the outer surface of the aluminum blower housing 461 is provided with a rubber layer 464; a plurality of cooling holes (not shown in the figure) are provided on one side of the aluminum blower housing 461, and the cooling holes (not shown in the figure) are directly opposite to the air outlet of the cooling fan 463. The aluminum blower housing 461 plays the role of electrostatic shielding inside the blower, and the rubber layer 464 can prevent external static electricity from entering the inside of the ion blower, thereby realizing the anti-static function of the ion blower. The setting of the cooling fan 463 and the cooling holes enables the blower to have good heat dissipation performance, avoiding the situation where the performance of the blower is reduced or even damaged due to temperature accumulation.

[0050] Among them, the lifting component 57 includes a base 571 and a lifting seat 572 arranged at the bottom of the device body 51, the backlight panel 56 is arranged on the lifting seat 572, and its light-emitting surface faces the light-transmitting inspection table 55, and a lifting scissors frame 573 is provided between the lifting seat 572 and the base 571, and the second driving mechanism is used to drive the lifting scissors frame 573 to rise and fall.

[0051] A group of first slide rails are respectively provided at both ends of one side of the base 571, and a group of first pulleys are respectively provided at both ends of one side of the bottom of the lifting scissors frame 573, which are slidably connected to the first slide rails, and the two ends of the other side of the bottom of the lifting scissors frame 573 are respectively hinged to the base 571; a group of second slide rails are respectively provided at both ends of one side of the lifting seat 72, and a group of second pulleys are respectively provided at both ends of one side of the top of the lifting scissors frame 573, which are slidably connected to the second slide rails, and the two ends of the other side of the top of the lifting scissors frame 573 are respectively hinged to the base 571; the first slide rail and the second slide rail are located on the same side.

[0052] When the hydraulic cylinder drives the telescopic shaft to extend and retract, the lifting scissors frame 573 will rotate around its hinge point. This rotational movement will simultaneously change the position of the pulleys at the bottom and top of the lifting scissors frame 573 on their respective slide rails, thereby pushing the lifting seat 572 up or down.

[0053] The device body 51 is provided with a display screen 58 and an air purifier (not shown). The display screen 58 and the air purifier are electrically connected to the control device. The display screen 58 is used to display the thickness of the OLED protective film, as well as the height of the second ion blower 53 and the backlight panel 56. The air purifier is used to remove harmful gases, odors, and finer particulate matter from the air in the inspection area, ensuring that the air in the inspection area meets a high cleanliness standard, which helps to accelerate the efficiency of OLED protective film inspection.

[0054] Several pneumatic clamps 7 for fixing the OLED protective film are provided on the edge of the light transmission inspection table 55; an air pump (not shown in the figure) is also provided on one side of the device body, and the air pump is connected to the pneumatic clamp 7 through an air pipe (not shown in the figure), and a vacuum valve (not shown in the figure) is provided on the air pipe.

[0055] The air pump serves as a power source, generating high-pressure gas by compressing air. When the air pump is activated, high-pressure gas is directly transmitted through the air pipe, which is then transported from the air pump. When the vacuum valve is opened, the high-pressure gas enters the pneumatic clamp 7, which clamps and secures the OLED protective film. When the vacuum valve is closed, the gas supply is cut off, and the pneumatic clamp 7 releases the OLED protective film. In this embodiment, the clamping surface of the pneumatic clamp 7 is aligned with the plane of the light-transmitting inspection table 55, ensuring that the pneumatic clamp 7 can be placed flat on the light-transmitting inspection table 55 after clamping the OLED protective film.

[0056] The bottom of the device body 51 is equipped with several height-adjustable support columns 59. Each support column 59 is equipped with a guide wheel 591, which is equipped with a locking mechanism (not shown). The guide wheel 591 and the locking mechanism facilitate the movement and parking of the inspection platform, increasing its convenience. The height-adjustable support columns 59 enable the device to be used by inspectors of different heights.
